VAPORIZING AND IGNITION DEVICE.

SPECIFICATION forming part of Letters Patent N o. 532,100, dated January 8, 1895.

Appnmion nea August 1e, 1894.

To-aZZ whom `it may concern:

Be it known that I, JOSEPH ROBISON, a citizen of the United States, residing at Greenbush, Rensselaer county, New York, have invented certain new and useful Improvements in Vaporizing and Ignition Devices; and I do hereby declare the following to be a full, clear,

vlo

and exact description of the invention, such as will enable others skilled in the art to which' it appertains to make and use the same, refer `ence being had to the accompanying drawing, and to the figures and letters of reference marked thereon, which form a part of this specilication.

Theobject of my invention is to providea new and 'improved vaporizing and'ignition device for oil or vapor engines. Y

In the drawing the gure shows a vertical".

sectional view of my device in operative construction. Y Y

The numeral `1 shows a casingpreferably attached to the top ofthe engine cylinder 2O forminga chamber'1' which is practically an extension of the cylinder. To the top, preferably, of casing l I ,fix a valve casing 2 hav-A ing an air inlet 19 and 'an oil supply pipe 9.- entering it, and containing an automatic acting valve 3, constructed asfollows: The valve Y stern 4 is tubular for. part of its length, thebalance being preferably solid. At the lower end ofthe stem 4 is a flange 3 havinga stud its under side.

3' depending fr'oxnits lower side, the bore of the stem 4 being formed through the stud 3" and its lower' end closedV by a plug d. About the stud is screwed the washer and preferably reinforced by a nut turned against The meeting faces of the flange 3 and washer 3 are groovedV or channeled, the grooves or channels 3 communiy eating. with the bore of the valve stem so that when a charge of oil is passed down the bore;` of the stem it will pass into the grooves 3 and out at their outer ends, which discharge Iso around the edgeA of the valve. The valve stem 4 passes into and through chambered plug 6, and surrounding the stem preferably is a plunger 5 flanged at its upper end pref-V erably, and abutting against a nut,8 turned on the stem, the valve 3, its stem 4 and the plunger 5 (being adjustable by means of nut' 8) being held in position by the coiled spring 7, the plunger and stem being vertically mov-v YSerial No. 520,536. A (No modali) is increased or diminished, the governor,

If the firing takes place too early I shorten vthetube 13 and if too late I lengthen it, but after the time of firing has been once correctly ascertained and the tube made of the proper length to govern the flring, Iclose the tube 13 preferably by a cap as it then needs no more attention. The tube 13 is lengthened by turning the cap upward, and

shortened by turning it downward, and as, if

a detailed description thereof is not deemedV necessary. The heat heats the ignition chamber or tube 12 to redness preferably.

rounding the tube 12 is a jacket 15 lined `with a nonconductor 14 preferably, consisting of ICO Surn,

asbestos in order to keep the tubes 12 and 13 as hot as possible.

The operation is as follows: The burner 16 being set in operation, the iiame is allowed to burn until the ignition tube is heated to redness and until the inner vaporizing tube 11 is heated sufficiently to vaporize the first few charges of oil. The fly Wheel of the engine is then revolved until the piston makes one or more suction strokes. As the piston makes a suction stroke,the suction opens or draws down valve 3, the stem 4 and the plunger 5, the plunger acting like a pump, compressing the charge of oil in chamber 18 and forcing it through port 5 down the tubular stem 4, and out through channels 3 in valve 3, and causing it to be sprayed against the heated sides of vaporizer 11, and at the same time a charge of air is sucked into the vaporizer 11 through opening 19 and the oil, vapor and air are thus mixed in the vaporizer and pass out of it and into tube 12, chamber 1 and the cylinder. 0n the compression strokeof the piston, the mixed oil vapor and air are compressed and forced back again into ignition chamber 12 and against its red hot sides Where it is ignited creating an explosion Which operates the piston. To the opening 1 is fixed the usual exhaust Valve used With ordinary gas or oil engines and as their construction is Well known, and they being in common use, a detailed description thereof is deemed unnecessary. On the exhaust stroke of the piston the products of combustion are discharged from the exhaust valve in the usual manner. As the explosions continue in the cylinder and in chamber 1 the heat engendered is sufficient to' keep vaporizer 11 sufficiently heated to cause it to vaporize any and all oil entering it, the tube 11 acting as a superheatcr as Well as a vaporizer, and after the engine has run for a short time vaporizer and igniter 11 is heated by the explosions in the cylinder to such a degree that it becomes a vaporizer and igniter combined, first vaporizing any oil that may enter it on the suction stroke of the pis ton, and igniting the mixed vapor and air on the compression stroke, and When so heated the temporary burner 16 may be shut off entirely and the engine continue to run. As vaporizer and igniter 11 is open to the inrush of the products of combustion of each explosion in the cylinder and is also externally surrounded by them, its full surface both exterior and interior are acted on directly by the heat in said products, thus allowing of its being quickly heated to the degree required. The object of having the exit end of vaporizer and igniter 11 project into the supplementary or outer igniter 12 is, that this end may become heated from the external burner 16 at the same time the outer or sup- 'plementary igniter 12 is being heated and to also provide an extended surface upon which to vaporize all oil entering vaporizer and igniter 11. The form of vaporizer 11 as shown may be modified if desired, as I do not confine myself to the form shown.
